fix: remove deprecated default cipher for golang >=1.22

[joshrwolf]

Closes #17571

newer versions of go remove the TLS_RSA_WITH_AES_256_GCM_SHA384 as an available cipher.

this PR simply removes it in favor of the existing default TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, which remains a valid default option for the existing go toolchain version, and future ones

Have you run make codegen? Which versions of Go does this apply for BTW?

[blakepettersson]

I see, golang/go#63413

[blakepettersson]

@joshrwolf I'll mark this PR as a draft until you run make codegen-local on your machine and commit those changes.

FYI, I had go 1.22 installed and running the codegen locally gave me errors with packages downloaded with go 1.22. After installing 1.21, re-downloading all the local toolings in dist/, I don't have the error anymore. Not sure if there is a bigger issue on upgrading argo to 1.22, but this might affect you.

I took the liberty, run codegen and pushed changes to the branch (make clidocsgen to regenerate docs only)
